DOOR-HANGER SPECIFICATION forming part of Letters Patent N 0. 723,922, dated March 31, 1903. Application filed August 2, 1901- Serial No. 70,594. (No model-J To all whom it may concern:

Be itknown that I, MARCIUS O. RICHARDS,

a citizen of the United'States, residing at Au rora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Door-Hangers, of which the following is a full, clear, and exact specification. Heretofore much difliculty has been experienced in preventing the nuts on the pendent bolts of door-hangers from automatically rotating and lowering the sliding doors sus-. pended thereby, and great difficulty has been experienced in preventing the truck of the door-hanger from working into a position oblique to the line of travel of the door, and thus binding the same.

The object of my invention is to provide cheap, simple, and effective devices for overcoming these difficulties. This I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a door-hanger having my improvements applied thereto. Fig. 2 is an end edge view of the same, showing the tram or track there for in cross-section. Fig. 3 is a plan view of theunder side of the door-plate used in connection therewith. Fig. 4 is a sectional View taken on dotted line 4 4 looking in the direc tion indicated by the arrows.

In the drawings, A represents an inverted channel-shaped track, the lower edges of the parallel walls of which are inturned to form gutters or ways for the wheels of the truck B to travel back and forth in. The truck B, as shown in the drawings, consists of a longitudinal web of metal, the ends of which terminate in transverse bosses on which the revolving axes of the wheels or rollers of the truck are journaled. In so far as the essential features ofmy invention are concerned, however, I do not desire to be confined to any particular shape of track or construction of truck, as it is obvious they maybe varied or difier entirely from the truck and track herein described and shown.

Secured at about the center of length of the truck, by means of a bolt (2, extending transversely through the bifurcations of its upper end, between which the web of said truck passes, is a hanger O. The manner of connectingthis hanger to the truck, as shown in the drawings, contemplates giving the hanger alimited amount of vertical play as well as a limited oscillatory movement or swing. This manner of connecting these parts is desirable 0 rather than necessary.

At a suitable point below the truck the bifurcations of the hanger merge into a pend- 6o ent screw 0, which extends down a suitable distance and is engaged by a flanged nut D, whose reduced upper portion occupies and is seated in an opening d in the supporting-plate E. This supporting-plate is adapted to be secured to the upper edge of a sliding door andto cover the recess 01 made in said door for the reception of the :lower end of the screw 0 and the flanged lower end k of nut D, which latter engages the supporting-plate E, and thereby supports the door to which said plate is attached.

Heretofore the movements of the door had a tendency under certain conditions to cause the truck to get into a position oblique to the line of its proper reciprocal course and bind the truck againstthe wall of the track, so that. it was hard to move'the door. This lateral deflection of the truck' supplemented by the vertical vibrationsof' the door often cause the nut D to unscrew, and thus lowers the door to an objectionable extent. The particular object of my invention is to overcome both of these defects, and particularly'the deflection of the truck from its true course, as by so doing the latter objectionthat due to the nut D unscrewing-is to a great extent overcome. I accomplish this by means of a pendent arm G, the upper end of which is preferably pivoted between two parallel lugs 0 g g, projecting from the edgesof the bifurcations of the hanger in the direction of the line of motion of the truck. The lower end of this pendent arm extends through a slot 6 in plate E, which extends longitudinally from 5 opening d, substantially as shown. The length of arm G may be suchthat its lower end will terminate in slot e. In such an event if the width of the arm is "just such that itcan operatively enter said slot this arm pre- I00 vents the accidentaf obliquity of the truck and keeps it traveling in the same plane of movement as the door and removes one of the means which heretofore contributed to cause the nut D to unscrew. I prefer, however, especially as the cost of so doing would practically add nothing to the cost of the fixture, to extend the lower end of arm G a suitable distance below the plate E (making allowance for the adjustability of the door higher or lower as the exigencies of the environments may require) and provide the circumference of the flange 7a of nut D with a series of niches or indentations h h, which are preferably located equal distances apart and are adapted to be engaged and entered by said arm to lock said nut against accidental rotation at any point to which it may be adjusted. If arm D were intended only to engage slot 6 to maintain the parallel relation of the door and truck, it could be rigidly attached to the hanger in such manner as not to interfere with the nut. As shown, it must have a limited movement to enable it to engage and disengage from the niches or indentations of the nut.

\Vhat I claim as new is 1. A doorhanger comprising a truck, a hanger pendent therefrom having its lower portion screw-threaded, a nut adapted to engage said screw-threaded portion, a supporting-plate adapted to be secured to the upper edge of a door having an opening therein through which the hanger extends and a longitudinal slot alining with said opening, and an arm depending from the superstructure of the hanger and adapted to enter said slot, substantially as set forth.

2. A door-hanger comprising a truck, a hanger pivotally connected thereto and pendent therefrom having its lower portion screwthreaded, a nut adapted to engage said screwthreaded portion, a supporting-plate adapted to be secured to the upperedge of a door having an opening therein through which the screw-threaded portion of the hanger extends and a longitudinal slot extending from said opening, and an arm pivotally connected to and depending from the upper end of said pendent hanger and adapted to enter said slot substantially as set forth.

3. A door-hanger comprising a truck, a hanger pendent therefrom having its lower portion screw-threaded, a nut adapted to engage said screw-threaded portion having a series of niches in the circumference thereof, a supporting-plate adapted to be secured to the upper edge of a door having an opening therein through which the screw-threaded lower portion of said hanger extends, and a longitudinal slot alining with said opening, and an arm pivotally connected to and depending from the superstructure of the hanger and passing through said slot and adapted to engage the niches in the circumference of said nut, substantially as set forth.

4. A door-hanger comprising a truck, a hanger pivotallyconnected thereto and pendent therefrom and having its lower portion screw-threaded, a flanged nut adapted to engage said screW-threaded portion of the same having a series of niches in the circumference of the flange, a supporting-plate adapted to be secured to the upper edge of a door hav ing an opening therein through which the screw-threaded portion of the hanger extends and a longitudinal slot alining with said opening, and an arm pivotally connected to and depending from the upper end of said hanger and passing through said slot and adapted to engage the niches in the circumference of the flange of said nut, substantially as set forth.

5. A door-hanger comprising a truck, a hanger pendent therefrom having its lower portion screw-threaded, a supporting-plate adapted to be secured to the upper edge of a door, down th rough which the screw-threaded portion of the hanger extends, a nut engaging said hanger below the plate, and a movable member connecting said door and hanger and supporting-plate to prevent the truck from getting oblique to the line of travel of the latter, substantially as set forth.
